3.However,the Bermuda Triangle is one of the two places on Earth in which a compass points towards true north.Line 5,Para 11) 译文但是在地球上有两个地方罗盘刚好指向真北，百慕大三角就是其中之一。 Explanation: 1)magnetic north:磁北（由磁罗盘所指示的北方，但在大多数地方并非正北方向） true north:真北（地球北极的方向，测量方向时的基准方向。另一处罗盘指向真北的地方 位于日本东海岸，被日本和菲律宾海员称为“魔鬼海域”。这一海域也以船只的神秘失踪 而闻名)。 2)“in which”为介词+关系代词，引导定语从句的结构，介词被提前了。这一结构在从句 中主要起关系副词的作用，即在定语从句中充当状语。 A.表示地点，时间和原因的“介词+which”分别相当于where,.when,why。 e.g.I have found the book in which the names of all the early satellites are mentioned.(=I have found the book.The names of all the early satellites are mentioned in it.) The earth on which/where we live is a planet. I'll never forget the day on which/when I joined the League. Is there any reason for which/why you should have a holiday B.介词的选择须考虑下列情况： 1)介词与先行词的习惯搭配 e.g.There is no way in which it could be brought back to the earth.(in与way是习惯搭配) 2)介词与定语从句中的动词，形容词的习惯搭配 e.g.These are the wires with which different machines are connected.(be connected with 是习惯搭配) e.g.The author with whom all of us are familiar will visit our company.(be familiar with 是习惯搭配) 注：复杂介词须保持其完整形式，常见的复杂介词有on the top of,in the middle of, in front of,in spite of,at the back of,because of. e.g.Sound is a tool by means of which people communicate with each other. They marched through the square,in the middle of which stood a monument. 4.This latest theory has yet to be proved but seems to offer a better explanation as to why Flight 19 and all the other planes,ships and people have disappeared in the Bermuda Triangle.Line 1,Para 13) 译文这一最新理论仍有待证实，但它似乎给第19飞行分队以及所有其他的飞机、船只和人 员为什么会在百幕大三角失踪提供了一种更好的解释。 Explanation: sto…(复合介词)“关于…，至于…，以…而论” 可置于句首或句中。根据句意，有时可不用译出。 asto..的语用场合： 1)表示涉及某点：sto与引出的词语常置于句末，表示“关于…方面”、“有关…之事”， 只涉及实际内容而不涉及讲话人的态度，并且常用于否定句之中。但为了突出要提及 的人或事情时，常将sto置前，以示强调。 e.g.He has no complaint as to salary. 工薪方面他没意见。5 3.
